CROSS REFERENCE TO RELATED APPLICATIONS

The present application is related to U.S. patent application Ser. No. ______ filed concurrently herewith by Peter H. Zecher, the inventor herein, entitled “BIRD DETERRENT DEVICE VANE,” the disclosure of which is hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention relates to devices adapted for use in deterring birds from alighting on objects. More specifically, the present invention relates to wind propelled bird deterrents particularly suited for use on marine craft, docks, golf courses, farms, and other locations where the existence of birds is undesirable or problematic. For purposes of simplicity, the remainder of this disclosure will generally focus on birds from the gull family and their alighting onto marine craft. However, it is to be understood that the invention is not so limiting, and is related to alighting of birds onto any object.

It is well known that birds, particularly those from the gull family, often alight on fixed objects such as marine craft for temporary perching. While perched, these birds often leave droppings that cause considerable damage to the craft. Although the damage is typically cosmetic in nature, due to the effects of uric acid contained in the droppings, the damage may be structural and may compromise the integrity of the craft. Even if merely cosmetic, the droppings are often cleaned up at considerable time and monetary expense. In either event, the droppings are detrimental and preferably avoided.

Numerous deterrents have been devised to prevent birds from alighting on fixed objects such as marine craft. Many of these deterrents rely on spikes or barbs to deter alighting altogether. Others rely on scare tactics by exhibiting characteristics which instill fear in the birds. Still others rely on movement and physical contact between the deterrent and the bird, so as to nudge the bird from its perch. One such deterrent is described in U.S. Pat. No. 3,292,319 issued to McCarthy.

Devices sold in accordance with the invention of U.S. Pat. No. 3,292,319 have proven to be effective in preventing birds from alighting on fixed objects. In particular, apparatuses built in accordance with that invention have been used effectively in the marine industry to prevent gulls from alighting on water craft.

As described in U.S. Pat. No. 3,292,319, a bird deterrent may comprise a plurality of arms extending from a rotatable hub, where each of the arms includes a vane assembly at its distal end. The vane assemblies may be adapted to cooperate with the wind to drive the arms in a circular manner in the hopes of either preventing birds from alighting altogether or nudging those that have previously perched with physical contact.

One feature of the invention described in U.S. Pat. No. 3,292,319 is that the arms may fold at the hub such that the arms may be placed adjacent to each other to reduce the overall span of the inventive device. This reduction in span is particularly useful when storing or transporting the device. In such folded condition, however, it has been found that vane portions of the vane assemblies often break because their range of motion relative to the arms is fixed between a range of approximately 45 degrees to 135 degrees relative to the arms, thus preventing the vanes from folding completely flat imparting a high degree of force on the vane hinge. This force often breaks the hinge.

The present invention has arisen to solve the issue of breakage during folding by providing for a bird deterrent device which permits the vanes to move into a position substantially parallel to the arms, such that the vanes will lay flat and not break when the device is folded and transported or stored. Other advantages over the prior art have also been realized.

DETAILED DESCRIPTION

In the following are described the preferred embodiments of the bird deterrent device in accordance with the present invention. In describing the embodiments illustrated in the drawings, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose. Where like elements have been depicted in multiple embodiments, identical reference numerals have been used in the multiple embodiments for ease of understanding.

As previously discussed, the bird deterrent device of the present invention is particularly suited for use with a marine craft to prevent birds, such as sea gulls, from alighting thereon. FIG. 1 depicts such an arrangement, where a bird deterrent device 100 is mounted to a marine craft A in the conventional manner. As is typical, the marine craft A of FIG. 1 comprises a hull B having a deck C. A cabin superstructure D is arranged on top of the deck C, where the cabin superstructure D comprises a canopy E at its uppermost portion. Typically, it is the canopy E upon which sea gulls prefer to alight and perch. Accordingly, a bird deterrent device 100 may be mounted to the canopy E to prevent birds from alighting or to shoo away those that have alighted and perched. Although not shown, bird deterrent device 100 may also be affixed to other areas of the marine craft A, such as the deck C. Notwithstanding, it is not necessary to cover the entire surface area of the marine craft as the bird deterrent device 100 also may assist in scaring away birds from alighting, even if they would not have otherwise made physical contact with the bird deterrent device 100 when perched.

FIG. 2A depicts a perspective view of a bird deterrent device 100 in accordance with a first embodiment of the present invention while FIG. 2B depicts a partially broken blown-up view thereof. As shown in FIGS. 2A and 2B, the bird deterrent device comprises four main components or categories of components; namely, a mounting member 102, a hub 104, arms 106, 108, and vane assemblies 110, 112. Generally, the mounting member 102 comprises features to permit attachment to a fixed object, such as a marine craft. The hub 104 may then be fitted over the mounting member 102, such that the hub 104 may freely rotate. A pair of arms 106, 108 may extend radially from the hub 104, where the arms culminate with vane assemblies 110, 112 adapted to propel the hub in a rotational manner upon application of a sufficient wind force. Such rotation prevents birds from alighting, either through direct physical contact or by scaring the birds.

More specifically, as shown in FIG. 3, the mounting member 102 may comprise a base 114 with an upright support 116 extending therefrom. The base 114 of the mounting member 102 may be circular, as shown, or may be configured into other shapes such as orthogonal or non-geometric. In addition, the base 114 may be rigid or soft. In the case of rigid bases, the base 114 may be configured from various plastics or metals. In the case of a soft base 114, the base may be formed from a fabric material with sand or other fine grained material therein, so as to form a bean-bag like structure. Although not shown, other bases 114 may also be utilized, such as clamps and blocks.

One factor in determining an appropriate base 114 to use is to understand the characteristics of the fixed object to which the bird deterrent is going to be mounted to, and the requirements of that mounting. For example, for temporary use, a bean-bag like base may be most appropriate. For more permanent uses, a rigid plastic base may be more suited, where the plastic base may be permanently secured to the fixed object on which the device is to be placed by, for example, adhesives or mechanical fasteners.

It will be appreciated that the base's 114 main function is to buttress the upright support 116. Yet, in certain embodiments, the base 114 itself may not be required. Rather, the upright support 116 may be affixed to a fixed object without the need for a base 114. For example, the upright support 116 may be cylindrical with exterior threads. The upright support 116 may therefore be threaded to a fixed object having a suitable recess with matching interior threads.

If provided with a base 114, the upright support 116 of the mounting member 102 may be affixed to the base by several means. In one example, the upright support 116 may be cantilevered from the base 114. To establish a strong relationship between the two, the base 114 may include a recess in which the upright support 116 may be placed. Adhesive components may then be placed within the recess along with the upright support 116 such that the upright support 116 is cantilevered from the base 114. Alternatively, the upright support 116 may be pressure fit within the recess, without adhesive.

In a preferred arrangement, as shown in FIG. 3, the upright support 116 may be threaded at its proximate end 118 closest to the base 114. The base 114 may include a recess having corresponding internal threads, such that the upright support 116 may be threaded to the base. A follower member 120, such as the wing nut shown in FIG. 3, may be threaded against the base 112. It will be appreciated that the follower member 120 pulls the threads of the upright support 116 against the threads of the base 112 so as to enhance friction between the two members. This relationship helps to prevent back-out of the upright support 116 during use.

The mounting member 102 therefore provides an upright support 116 which is preferably, but not necessarily, vertical. In ideal embodiments, the upright support 116 is as near vertical as possible.

At the distal end 122 of the upright support, away from the base 112, the upright support 116 preferably culminates in a point 124. As will be discussed, the point 124 permits the hub 104 to rotate about the longitudinal axis 126 of the upright support 116 with minimal frictional loss.

FIG. 4 depicts a perspective view of a hub 104 in accordance with certain aspects of the present invention. As shown, the hub 104 may comprise an upper portion 128 and a lower portion 130. The lower portion 130 is preferably cylindrical, with a hollowed recess 132. The hollowed recess 132 is preferably sized slightly larger than the upright support 116 of the mounting member 102, such that the lower portion 130 of the hub 104 fits over the upright support and is free to spin or rotate about the longitudinal axis 126 thereof. In this regard, the hollowed recess 132 of the hub 104 may culminate in a point 134 matching the point 124 of the upright support 116, so as to minimize friction between the two components and promote smooth rotation.

The upper portion 128 of the hub 104, which is also preferably cylindrical, may taper from the lower portion 130 at a tapered section 136 such that its diameter is greater than that of the lower portion. The upper portion 128 may also culminate with a flat top 138. The flat top 138 may be separated into two roughly equal-sized sections 138 a, 138 b by a barrier wall 140 extending along the flat top and through a midpoint of the generally cylindrical hub 104. The barrier wall 140 may include a pair of apertures 142, 144 to facilitate mounting of the arms 106, 108 thereto. Additionally, the hub 104 may include posts 146, 148 extending from the flat top 138 to assist with aligning of the arms 106, 108.

FIG. 5 depicts a hub 104 being placed over the upright support 116 of a mounting member 102 along the direction of arrow A. It will be appreciated that the lower portion 130 of the hub 104 is preferably shorter than the overall length of the upright support 116, such that the bottom edge 150 of the hub 104 does not interfere with the top surface 152 of the base 114 of the mounting member 102.

As further shown in FIG. 5, the hub 104 may include provisions for rotatably mounting the arms 106, 108. Preferably, the proximal ends 154, 156 of each arm 106, 108 may be affixed to the barrier wall 140 by a mechanical fastener, such as a bolt 158 extending through the respective arm 106, 108 and aperture 142, 144 of the barrier wall. In this regard, the arms 106, 108 may rotate about their respective mechanical fasteners 158 such that the arms may be placed in a first position, in which the arms are rotated away from each other for use of the bird deterrent device 100 as a bird deterrent, as shown in FIG. 2, or toward each other such that the arms are generally aligned along the longitudinal axis 126 of the upright support 116 (or where the axis would be if the mounting member 102 is not connected to the hub 104), or the axis of lower portion 130 (not shown), for storage or transport of the bird deterrent device. This position is shown in FIG. 6. The bolt 158 may have a nut 160 mounted thereon to ensure that the respective arm 106, 108 remains attached. The hub 104 may also include posts 146, 148 to assist with aligning of the arms 106, 108. As shown, the arms 106, 108 may be secured between the posts 146, 148 and the barrier wall 140 when the arms are opened for use of the bird deterrent device as a bird deterrent. Thus, the posts 146, 148 assist with aligning the arms even if the mechanical fastener, such as bolt 158, is not completely tight.

It will be noted with respect to FIG. 6 that the arms 106, 108 may not be straight, but may include bent sections 106 a, 108 a. The bent sections 106 a, 108 a assist in permitting the device to fold when the arms are brought together in the second position by off-setting one vane assembly 110 from the other 112.

FIG. 7 depicts an exploded view of a typical vane assembly, for example vane assembly 112, in accordance with one embodiment of the present invention. It will be appreciated that the vane assemblies 110, 112 are typically included at the distal ends 106 b, 108 b (FIG. 2A) of the respective arms, so as to be distant from the hub 104 and mounting member 102. This relationship ensures that a maximum torque will be applied to the hub 104 to spin the hub on the upright support 116 even in the mildest wind conditions.

As shown in FIG. 7, a typical vane assembly 112 may comprise a vane 162 having a main portion 164 and an extension member 166. The main portion 164 of the vane 162 may be orthogonal as shown, or may be configured to various other shapes. Preferably, the main portions 164 of the vanes 162 are planar such that their design will incorporate a relatively large surface area capable of acting as a sail to catch the wind.

FIG. 11 depicts a bird deterrent device 100′ having vane assemblies 110′, 112′ in accordance with a second embodiment of the present invention. In FIG. 11, the vanes 162′ are formed into the shape of a cat or owl. It will be appreciated that such animals are natural predators of birds, and tend to scare away the pests through emotional scare tactics even if physical contact between the pest and the bird deterrent device 100′ is not made. Other psychological scare tactics may also be utilized, such as using bright or metallic colors on the vanes 162′ which tend to reflect the light and “sparkle,” thus scaring away the pests.

Referring back to FIG. 7, it is shown that a vane assembly 112 may further comprise a post 168 and associated hardware, including an upper cap 170, a lower cap 172, a nut 174, and a spring 176. Preferably, the extension member 166 of the vane 162 includes an aperture 178 through which the post 168 may be inserted. The post 168 may include a threaded upper portion 180 and a threaded lower portion 182 separated by an unthreaded middle portion 184, where the threaded upper portion 180 and threaded lower portion 182 extend from the aperture 178 of the extension member 166 when the post 168 is inserted therethrough, the upper threaded portion from one end and the lower threaded portion from the other. The arm 108 may also include an aperture 186 at its distal end 108 b through which the threaded lower portion 182 of the post 168 may extend.

To install a vane 162 upon an arm 108, one may insert the post 168 without upper cap 170 through the aperture 178 of the extension member 166 and then thread the nut 174 onto the lower threaded portion 182 of the post 168 such that the nut is threaded a considerable distance toward the unthreaded middle portion 184, at least far enough to permit the threaded lower portion 182 to fully penetrate the arm 108 with enough threads exposed to permit the lower cap 172 to the threaded thereon. The lower threaded portion 182 may then be placed through the aperture 186 of the arm 108 and the lower cap 172 threaded thereon.

The spring 176 may then be slid onto the post 168 over the upper threaded portion 180 such that the spring 176 may rest against an upper edge 188 of the extension member 166 of the vane 162. The upper cap 170 may then be threaded onto the upper threaded portion 180 of the post 168 to secure the post and vane 162 to the arm 108.

Preferably, the fitment of the components is such that the vane 162 may rotate about the post 168. For example, the post 168 is preferably sized to a diameter which is slightly smaller than the diameter of the aperture 178 through the extension member 166 of the vane 162. In addition, the post 168 is preferably sufficiently long such that the spring 176 is not either fully compressed, or compressed enough to exhibit sufficient force on the vane 162 to prevent rotation thereof.

The main portion of each vane 164 is also preferably provided with a pair of blocking members 190, 192 (FIG. 8D), with a first blocking member 190 on a first side 194 of the vane 162 and a second blocking member 192 (FIG. 8D) on a second side 196 (FIG. 8D). The blocking members 190, 192 are preferably shaped in the general form of a triangle, with a base 198 at the vane and a rounded distal peak 200.

As shown in FIGS. 8A-8D and 9A-9D, the vane 162 is designed to be moved from a first position where the vane is substantially parallel to the arm 108 (the first position is shown most clearly in FIG. 8A) and a second position in which the vane is generally perpendicular to the arm (the second position being shown most clearly in FIG. 9E). In the first position, the main portion 164 of the vane 162 sits entirely above the level of the arm 108. In order to be placed in such position, the spring 176 may be compressed and the vane 162 lifted and rotated relative to the arm 108 such that the blocking members 190, 192 at the lower portion of the vane 162 are above the distal end 108 b of arm 108. The vane 162 may then be released where the force of the spring 176 may assist with maintaining the vane in such position. In addition, the bottom surface 202 of the blocking members 190, 192 may be provided with a pair of locking tabs 204, 206. The locking tabs 204, 206 and their relation to the blocking members 192, 194 and arm 108 are best shown in FIG. 8C.

As shown, a first locking tab 204 may be shaped substantially as a right-angle triangle, with the hypotenuse 208 facing away from the bottom surface 202 of the vane 162 and the shortest leg 210 adjacent the middle of the vane, generally parallel to the length of the post 168. The second locking tab 206 may be much smaller, and may comprise a simple raised bump. It will be appreciated that the locking tabs 204, 206 work in a coordinated effort to maintain the vane 162 in the first position.

As stated previously, in order to move the vane 162 into the first position, the vane may be lifted with respect to the arm 108 to compress the spring 176. The vane 162 may then be rotated such that the vane is parallel to the arm 108. This rotation is preferably conducted in a direction toward the second locking tab 206, such that the second locking tab may be lifted over the arm 108. Upon continued rotation, the shortest leg 210 of the first locking tab 204 will abut the arm 108 to prevent further rotation. Upon release, the spring 176 will push down on the vane 162 and position the arm 108 in the well 212 created between the two locking tabs 204, 206, thus holding the vane in the first position.

To move the vane 162 to the second position, one may lift the vane to again compress the spring 176, and then rotate the vane over the second locking tab 206 until the blocking member 192 clears the arm 108. The vane 162 may then be released where the spring 176 will push the vane into position alongside the arm 108, such as shown in FIGS. 9A-9D.

Once in the second position, and as previously discussed, the vane 162 may be permitted to rotate about the post 168 within the limits defined by the blocking members 190, 192. This angle of rotation A is shown in FIG. 9E, and may be approximately a total 90 degrees in preferred embodiments, leaving outside angles of 45 and 135 degrees with respect to the arm 108. In other embodiments, the angle may be anywhere from approximately 1 degree to nearly 180 degrees.

The angulation of the vane 162 relative to the arm 108 previously discussed permits the transfer of energy from the wind into the bird deterrent device 100 to spin the arm 108 and hub 104 about the mounting member 102. For example, at any one time, certain vanes may be driven by the wind. As shown in FIG. 10, the wind may blow from direction W. For ease of reference, the wind driven vanes will be identified by the symbol DV (driven vane) and the non-driven vanes by the symbol NDV (non-driven vane). As will be shown, the driven vanes DV may be driven through approximately 270 degrees of rotation, as shown by angle A.

Assuming a starting position at A-A, the downwind vane will be displaced by the wind from the position shown by the dashed lines to the position shown by the fixed line. This vane will thereafter be driven by wind W to rotate the bird deterrent device 100 to the position indicated by B-B. The upwind vane at position A-A faces directly away from the wind, and is therefore non-driven NDV. At position B-B, the driven vane continues to drive the bird deterrent device through its rotation on to position C-C. In addition, the vane which was a non-driven vane at position A-A becomes a driven vane DV at position B-B due to the angulation of the vane relative to the wind. In this respect, two vanes of the bird deterrent device are driven vanes DV when in position B-B. Moving to position C-C, it is shown that the downwind vane rotates to a position facing away from the wind W, and becomes a non-driven vane NDV while the upwind vane continues to be driven DV, thus rotating the bird deterrent device 100 to the position indicated by reference D-D. In position D-D, the vanes retain their status from position C-C as either a driven vane or non-driven vane, thus rotating the bird deterrent device back to the position indicated by A-A, to start the process over again.

As shown and described, the inventive bird deterrent device 100 therefore serves to spin or rotate about the upright support 116 to deter birds from alighting upon a fixed object, or to shoo those that have previously perched, in conjunction with the force of the wind. Additional features of the bird deterrent device 100 allow the device to fold for transport or storage.

FIG. 12 depicts an alternate embodiment of a hub 104′ in accordance with certain aspects of the present invention. It will be appreciated that the hub 104′ generally operates in a similar manner, and serves a similar function as the hub 104 depicted and described with respect to FIG. 4.

As shown, and as is similar to the hub 104 depicted in FIG. 4, the hub 104′ depicted in FIG. 12 comprises an upper portion 128′ and a lower portion 130′. The lower portion 130′ is preferably cylindrical, with a hollowed recess 132′. The hollowed recess 132′ is preferably sized slightly larger than the upright support 116 of the mounting member 102 (FIG. 3), such that the lower portion 130′ of the hub 104′ fits over the upright support and is free to spin or rotate about the longitudinal axis 126 thereof. In this regard, the hollowed recess 132′ of the hub 104′ may culminate in a point 134′ matching the point 124 of the upright support 116, so as to minimize friction between the two components and promote smooth rotation. The upper portion 128′ of the hub 104′, which is also preferably cylindrical, may taper from the lower portion 130′ at a tapered section 136′ such that its diameter is greater than that of the lower portion.

In a departure from the arrangement of the hub 104 depicted in FIG. 4, the hub 104′ depicted in FIG. 12 may include three barrier walls, barrier wall 140′ and two exterior barrier walls 214, 216, separated by two sloped upper surfaces 218, 220. As will be discussed later, the two sloped surfaces 218, 220, may slope in different directions.

The exterior barrier walls 214, 216 may include apertures 222, 224, through which screws (not shown) may be driven. A first one of the screws may penetrate through one of the exterior barrier walls, wall 216 for example, at aperture 224 and then through an arm, for example arm 106, before finally penetrating the barrier wall 140′ at aperture 142′. It will be appreciated that the other arm 108 may be secured by utilizing aperture 222 of exterior wall 214 and aperture 144′ of barrier wall 140′. In this regard, the mating of the arms 106, 108, with hub 104′ will typically be more secure than the mating of arms 106, 108 with hub 104. This relationship is such because the screw (not shown) will be cantilevered in the first example and secured at both its proximal and distal ends in the second example.

As previously stated, the hub 104 includes sloped surfaces 218, 220. These surfaces are sloped in different directions, such that the low end of one is adjacent the high end of the other. It will be appreciated that the arms 106, 108 may rest against the sloped surfaces 218, 220 to project the arms out at a desired angle. When so sloped, the arms 106, 108 may not include bent sections 106 a, 108 a, as the sections may not be required to project the arm in a preferred direction. Alternatively, the surfaces 218, 220 may not be sloped and the arms may or may not include the bent sections 106 a, 108 a.

As with hub 104, hub 104′ may be placed over the mounting member 102 such that the upright support enters the hollowed recess 132′. The hub 104′ may then rotate about the upright support to utilize the inventive device.
